The Roland TR-606 Drumatix is a programmable analog synthesis drum machine built by the Roland Corporation from 1981 to 1984. It was originally designed to be used with the Roland TB-303, a monophonic analog bass synthesizer, to provide a simple drum and bass accompaniment to guitarists without backing bands.
The TB-303 and TR-606 launched in 1981 as a matched pair to provide solo artists the chance to practice without other individuals, solely using the TR-606 and TB-303 as drums and bass lines to practice to, but the programming and artificial sounds made the boxes uncomfortable to use and they soon lost their luster. The group was doomed to an early demise as popular music soon shifted to sampled drum sounds and real bass lines for hit songs, as sample capabilities were the newest development of the late 1980s. At one time, the TR-606 could be found in pawn shops for as little as US$50; since the resurgence in popularity of analog drum sounds for electronic music, however, the TR-606 will commonly sell for US$400 to US$500.
The TR-606 was used by punk rock/noise rock band Big Black and was credited on their records as a member named "Roland." Steve Albini later reflected on the TR-606: "When I first got the 606 I carried it around and listened to it like a Walkman, and over the course of a day I would gradually build and re-build a rhythm until it was satisfying to listen to on its own... Drum machines can be cool instruments with a lot of character. I was always disappointed when I heard one being used clumsily, which was most of the time."
The Scientific Americans, based in Northampton, Mass., used the 606 as one of three analog drum machines in two band lineups, live and in the studio. The other two drumboxes were a Roland CR-78 and a Roland DR-55 Dr. Rhythm.
It is on the flexi-disc "Beyond Fiscal Distress" and on the cassette album "Load & Go" (ROIR A-111).
The Sisters of Mercy also used it on their early records, where it was credited as a band member named "Doktor Avalanche." Orchestral Manoeuvres in the Dark had it listed in the liner notes of their album Dazzle Ships. Nine Inch Nails used it in their hit single "Closer" from the album "The Downward Spiral" and Dave Rowntree of the Britpop band Blur uses one on the track "On Your Own" from their 1997 self-titled album Blur.
Outside of rock music, the TR-606 was commonly used by electronica artists Plastikman, Aphex Twin, Mike Ink, and Autechre. Even artists that preferred breakbeats to four-on-the-floor rhythms used it, seen when 4Hero credited the TR-606 on its well-received album Parallel Universe. Another example was Massive Attack's 1994 album Protection, which prominently used the machine on some tracks, and the CD booklet included a photo of the TR-606 connected to a TB-303. The Swedish electronic band Covenant used it extensively for most of their career, citing it as "one of the most beautifully distortable drum machines ever made".
The TR-606 has six synthesized sounds: Bass Drum, Snare Drum, Hi Tom, Lo Tom, Cymbal and Open/Closed Hi Hat.
An additional function labeled accent serves to modify the volume of the entire drum mix on a given beat. This allows, for example, a louder beat 4 in a simple drum pattern: boom-chik, boom CHIK. There is no "swing" parameter on the TR-606. The output is mono.
The Lo Tom and Hi Tom tracks have outputs to trigger an external sound source.
When the trigger output is in use, the corresponding internal sound still functions normally. The tom track could be employed, for example, to trigger a kick drum synth module as the Scientific Americans did.
